Question

determine if the equation y = - 3 represents a horizontal line or a vertical line. then graph the line and identify
part: 0 / 4
part 1 of 4
the equation y = - 3 represents a horizontal line.
part: 1 / 4
part 2 of 4
the line select y - intercept and select x - intercept.

Explanation:

Step1: Recall line - type rules

In the coordinate - plane, an equation of the form $y = k$ (where $k$ is a constant) represents a horizontal line. Here $k=-3$, so $y = - 3$ is a horizontal line.

Step2: Find the y - intercept

The y - intercept is the point where the line crosses the y - axis. For the line $y=-3$, when $x = 0$, $y=-3$. So the y - intercept is $(0,-3)$.

Step3: Find the x - intercept

The x - intercept is the point where $y = 0$. For the line $y=-3$, since $y$ is always $-3$ and never $0$, there is no x - intercept.

Answer:

Part 1 of 4: horizontal
Part 2 of 4: has a; has no
